How to Tell If a Hamster Is Sick: Diagnosis Methods and Advice
To determine if a hamster is ill, you need to comprehensively observe changes in its behavior, physiology, and environment. Below are specific judgment methods and response suggestions:
I. Common Sick Symptoms
Respiratory Abnormalities
Sneezing
Runny nose (clear or pus-like discharge)
Rapid breathing or making "puffing" sounds
In severe cases, open-mouth breathing and obvious chest heaving may occur
Eye and Nose Issues
Red, swollen eyes with increased tearing or discharge
Damp, crusty fur around the nose
Behavioral Changes
Lethargy and reduced activity (e.g., no longer using the exercise wheel)
Huddling in corners and slow reaction
Abnormal aggression or irritability (e.g., biting when touched)
Appetite and Weight
Refusing food or sudden decrease in food intake
Noticeable weight loss
Fur and Body Condition
Rough, dull fur
Body trembling or convulsions
II. Severe Symptoms Requiring Emergency Vet Care
Difficulty breathing, convulsions, persistent vomiting, or diarrhea
Abnormal body temperature (ears or abdomen feel hot to the touch)
No improvement or worsening of symptoms within 24 hours
III. Daily Observation and Prevention
Environmental Management
Maintain a temperature of 20-25°C, avoid dampness and direct cold drafts
Clean the cage and replace bedding regularly
Health Monitoring
Record daily food intake, activity time, and waste status
Compare with the hamster’s normal behavior (e.g., nighttime activity level)
Isolation and Care
In multi-hamster households, isolate sick hamsters to prevent cross-infection
For mild symptoms, try warmth therapy + nutritional supplements (e.g., vitamin C)
IV. Notes
Do Not Misuse Medications
Human cold medicines (such as Banlangen) must be used under the guidance of a veterinarian.
Distinguish Between Allergies and Illness
Sneezing may be caused by irritants like bedding or perfume—always check for allergens.
If abnormalities are found, it is recommended to consult a professional exotic pet veterinarian first. Hamster illnesses progress rapidly, and delays can be fatal.
